Sale with Multiple Operating Unit

On a sales order you get a new "Internal Quote Requests" tab where you can ask another operating unit to quote the same deal. Each request is an "Internal Quote" record with its own operating unit, expected date, notes and a list of products with quantities, unit prices and subtotals.

Business rules built into the code: - You cannot create an internal quote for the same operating unit as the sales order; Odoo blocks it with an error. - Only one internal quote per operating unit and sales order is allowed. - When you pick a product on an internal quote line, the description, unit of measure and unit price are filled in automatically, and the subtotal is recalculated from quantity times unit price. - Pressing "Send" on a request moves it to the Sent state and creates a CRM opportunity for the target operating unit, using the sales team linked to that unit. If the unit has no sales team, Odoo shows an error. - The opportunity description is built from a template configured per company under Settings > Companies, on the "Operating Units" tab. - Changing the expected date updates the deadline of the linked opportunity, and changing the opportunity deadline updates the expected date of the request.

Sales users can read all operating units, and the new internal quote models are available to the Sales / Salesman group.
